Layer Details
Quilted Cover
A soft, viscose quilted cover designed to enhance breathability. In practice that means a fresher-feeling sleep surface rather than one that traps warmth.
Profiled Foam
A generous layer of profiled foam that softens with your body's warmth and contours to your curves. You should feel gentle pressure relief at the shoulders and hips rather than a flat, unyielding surface.
Natural Wool
Natural wool adapts to your body shape while adding a touch of bounce. Wool is naturally temperature-regulating, which means it helps you stay warm in winter and cooler in summer.
Pocket Springs
Individually pocketed springs work completely independently of one another, which means support tailored to each part of your body. It also reduces motion transfer, so you feel less of a partner's movement.

Key benefits
- Room when children climb in: You get 90cm each for two people sharing, which means a child who joins you at night finds a gap in the middle instead of landing on top of someone.
- Distance from a restless partner: The pocket springs move independently to cut down on felt movement, and the UK super king adds 15cm more each than the UK king, so a sprawling partner has further to travel.
- Space for a large dog: At 180cm wide, a big dog can settle at your feet or along one side while you both keep a fair share of the sleeping surface.
- Wool helps a crowded bed: More bodies in bed means more warmth, and the wool layer helps regulate temperature, which means a busy UK super king should feel a little less stuffy by morning.
- In proportion in a large room: In a period property or a generous master bedroom, the UK super king's 6ft width looks right where a UK king can seem slightly lost.
This size suits you if...
You share with a partner who tosses and turns, or with children and dogs who tend to arrive before morning, and your bedroom comfortably clears our suggested minimum of 3m x 2.9m.
Consider another size if...
Your bedroom falls short of 3m x 2.9m, or it's usually just the two of you sleeping soundly. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's
Is a Spring King Wool Luxury Pocket UK super king big enough for two adults and a child?
For a child who joins you now and then, yes. The UK super king measures 180 x 200cm and gives 90cm each for two people sharing, so a small child has somewhere to settle. Three every night will feel snug, but this is the widest size this mattress comes in.
Spring King Wool Luxury Pocket UK super king or UK king: which should I get?
The UK super king is 30cm wider than the UK king and the same length, giving 15cm more each for two sharing. That extra width matters most with a restless partner or regular visitors. If space is tight, the UK king needs at least 2.7m x 2.9m, against our suggested 3m x 2.9m for the UK super king.
Does a super king help if my partner moves a lot in their sleep?
Yes, in two ways. The pocket springs work independently, which means less of your partner's movement reaches your side. The UK super king then adds physical distance, with 90cm each. With a very restless sleeper, space does more than any comfort layer: a partner who sprawls simply has further to go before reaching you.
What should I check before ordering a UK super king mattress?
Check how the bedroom door swings and whether the landing has a tight turn, because a 180cm-wide mattress that is 32cm deep takes some manoeuvring. Budget for new bedding too. You'll need super king sheets and a 260 x 220cm duvet, so your current set is unlikely to fit.
